General Electric Material B50A365 identifies a Chromium-Niobium alloy steel used for compressor blading, turbine blading, and forgings.
This specification contains the following classes:B50A365A, B50A365A1, B50A365B, B50A365, B1B50A365C, Electric furnace material, heat treated for final properties Electric furnace material, annealedConsumable - Electrode remelt material, heat treated for final propertiesConsumable - Electrode remelt material, annealed Forgings for Non-bucket applications - Consumable Electrode remelt material, heat treated for final properties.
Material shall be heated to a temperature of 2000-2050°F (1095-1135°C) and held at temperature for sufficient time to assure uniform temperature within the load and each part thereof. The material shall then be quenched in oil or rapidly moving air, as approved in the manufacturing process plan,to a temperature below the Mf martensite finish temperature, to assure complete transformation. Material made to Classes A and C and material that is made to Class B without straightening or cold finishing shall then be uniformly heated to a minimum tempering temperature of 1185°F (640°C), and held for the time necessary to achieve all of the required properties.

Y1Cr18Ni9 | GB | China | Improve the machinability, ablation resistance. Suitable for automatic lathe production of bolt and nut |
1Cr18Ni9 | GB | China | High strength after cold forming, but elongation than 1 cr17ni7 slightly worse. Used in architectural decoration parts |
1Cr18Mn10Ni5Mo3N | GB | China | Of urea with good corrosion resistance, can produce urea corrosion of the equipment. |
1Cr17Ni7 | GB | China | High strength after cold forming. Used in railway vehicle, conveyor belt, bolt and nut, etc |
Y1Cr18Ni9Se | GB | China | Improve the machinability, ablation resistance. Suitable for automatic lathe production of rivets, screws |
0Cr18Ni9 | GB | China | Seamless stainless steel tubes for boiler and heat exchanger |
00Cr19Ni10 | GB | China | Carbon content lower than 0Cr19ni9 steel, excellent intergranular corrosion resistance, is used for welding after the class is not processed parts |
1Cr17Mn6Ni5N | GB | China | Nickel steel grade, instead of number 1 cr17ni7 and magnetism after cold working, used in railway vehicle, etc |
1Cr18Mn8Ni5N | GB | China | Nickel steel, instead of 1cr18ni9 |
0Cr19Ni9N | GB | China | Based on 0cr19ni9 plus N, strength increase and the plastic is not down. Reduce the thickness of the material. As a structure with strength components |
0Cr19Ni10NbN | GB | China | Based on zero cr19ni9 plus N and Nb, with better than 0 cr19ni9 properties and USES |
00Cr18Ni10N | GB | China | In 00cr19ni10 adding N, on the basis of the above grades also features, use the same as the 0 cr19ni9n, but better intergranular corrosion resistance |
1Cr18Ni12 | GB | China | Compared with 0 cr19ni9, processing low hardenability. Used for spinning processing, special drawing, cold heading |
0Cr23Ni13 | GB | China | Corrosion resistance and heat resistance are better than 0cr19ni9 |
0Cr25Ni20 | GB | China | Oxidation resistance is better than 0cr23ni13. Mostly used as heat resistant steel |
0Cr17Ni12Mo2 | GB | China | Seamless stainless steel tubes for boiler and heat exchanger |
1Cr18Ni12Mo2Ti | GB | China | Seamless stainless steel tubes for boiler and heat exchanger |
0Cr18Ni12Mo2Ti | GB | China | Seamless stainless steel tubes for boiler and heat exchanger |
